Thank you @niels
IMHO it makes sense, at least for the use case that made you do it, and it’s exactly what I was testing and talking with @jawn on the other thread over the weekend.
Maybe there is some way to make this not Spotify specific (this requires Premium).
My skills are very limited to go anywhere, but I’m interested in attempting to integrate Lyrion Music Server and Squeezelite player in the same way. The overall architecture seems quite similar.
